Found something similar in size to Otter 2000, at Wegman's with the back to school seasonal stuff.Cheap for $2.49. Amazon wants $3.29. UK sells them for 2.99 BP.Not polycarbonate, probably not waterproof and you can't drive over it with a truck. It does have a gasket though.But, the 2 compartments can each hold an UNO and a half size breadboard, with a little room to spare.
